Ruling that water from the Sacramento-San Joaquin River Delta is important not just for people but also for the fish that swim in it, a federal appeals court on Monday backed environmental restrictions on deliveries to urban Southern California and San Joaquin Valley agriculture.

A panel of the U.S. 9th Circuit Court of Appeals reversed most of a lower court ruling in a long-running legal battle over endangered fish protections in the delta, the hub of California’s water system.
The appeals decision was issued in one of two lawsuits filed by San Joaquin Valley irrigation districts — including the Westlands Water District — and the Metropolitan Water District of Southern California challenging federal protections that at times limit pumping from the delta to the big aqueduct systems that carry water south.

Though the water districts won at the U.S. District Court level in the two cases, the 9th Circuit has now unraveled both of those victories.
Monday’s decision upheld a set of environmental restrictions imposed in 2009 by the National Marine Fisheries Service to protect imperiled chinook salmon, steelhead and green sturgeon that migrate through the delta, along with a small population of orca whales that prey on salmon.

Noting that “people need water, but so do fish,” the 80-page opinion echoed another 9th Circuit decision issued this year that affirmed delta smelt protections adopted by the U.S. Fish and Wildlife Service.

As in the smelt case, the appeals judges concluded that U.S. District Judge Oliver Wanger overstepped legal bounds when he relied on thousands of pages of outside scientific opinion to invalidate many of the environmental restrictions.

Judge Richard Tallman, who wrote the opinion, said the three-judge panel agreed that the fisheries service “used the best scientific data available, even if that science was not always perfect.”

Major urban and farm water districts that get supplies from the delta have for years attacked the salmon and smelt protections in the courts and the political arena. The water contractors argue that federal fishery agencies focus too much on the effects of the delta pumping operations while ignoring other harms to native species, such as pollution and predation by non-native fish.

Bob Muir, spokesman for the Metropolitan Water District of Southern California, which imports delta water to the Southland, said Monday’s decision was not surprising, given the ruling in the smelt case.

Metropolitan and a number of other agencies have petitioned the U.S. Supreme Court to review the smelt decision. The high court in recent years has declined to take up other California water cases. A decision on the request is expected next month.

The appeals opinion “is likely to be the last word. But you never know,” said Drew Caputo, vice president of litigation at Earthjustice, which represented fishing and environmental groups that intervened in the salmon case.

Caputo called Monday’s opinion “a pretty resounding affirmation by the judges that the [fisheries service] did the right thing when it protected the salmon.”

In a departure from the detailed parsing of environmental law that made up most of the opinion, Tallman opened with a passage from “East of Eden,” John Steinbeck’s novel about California’s Salinas Valley: “And then the dry years would come … The land dried up and the grasses headed out miserably a few inches high and great bare scabby places appeared in the valley.”

“The same can be said for California’s Central Valley,” Tallman wrote, adding that the salmon case was about competing demands for delta water.

“This water is essential to the continuing vitality of agriculture in the Central Valley, and some 25 million Californians depend on it for daily living. But that water is also an important habitat for thousands of river and anadromous fish, many of which are endangered.”

WASHINGTON — (Saving Seafood) December 19, 2014 — After Congress voted unanimously this week to extend a three year moratorium exempting commercial fishing vessels 79 feet and under from needing incidental discharge permits from the Environmental Protection Agency (EPA) for deck washing, the President signed the extension into law on Thursday.

Yesterday, President Obama signed into law the “Howard Coble Coast Guard and Maritime Transportation Act of 2014,” exempting small fishing vessels from the EPA’s National Pollutant Discharge Elimination System (NPDES) discharge permit requirements. The law extended the exemption provision for three years on the very day that the EPA’s NPDES permit requirements would have taken effect.

The regulation was intended to prevent fuels, toxic chemicals, or hazardous waste from entering the water. Senator Lisa Murkowski (R-Alaska) told the Alaska Journal of Commernce that requiring a permits for fishermen to hose down a boat is overkill – especially when recreational boats, including mega-yachts – are exempt from the rule.

“We want to abide by environmental regulations that make sense,” Murkowski told the Journal, “But I don’t think any of us believe it should be a requirement for a fishermen who has had a good day out on the water, and they are cleaning up the boat, and hosing slime and maybe some fish guts off the deck and that then becomes a reportable discharge to the EPA…. Let’s use some common sense here.”

The research ship Ocean Starr returned to San Diego Wednesday, completing NOAA Fisheries’ first comprehensive survey of whales, dolphins and porpoises and the marine ecosystem off the West Coast in six years. Highlights of the four-month survey included unusual marine mammals and birds drawn by warm ocean conditions, and the first offshore tests of an innovative new system for remotely counting marine mammals through sound.

“You don’t know what you will find until you are out on the ship, which is what makes it so important,” said Jay Barlow, chief scientist of the California Current Cetacean and Ecosystem Assessment Survey that stretched from California north to Washington. “This has been a very interesting and surprising survey because we’ve seen species we wouldn’t expect, which gives us information about their distribution as well as about current ocean conditions.”

The Survey led by the Southwest Fisheries Science Center identifies and counts cetaceans, seabirds and marine turtles using high-powered binoculars and towed listening arrays. The team also uses a series of specialized nets and oceanographic sampling gear to survey microorganisms that provide important clues about ocean conditions as well to monitor the physical environment through which the ship is traveling. In some cases researchers take tiny biopsies from whales and dolphins for genetic studies of population structure, foraging habits and health.

Scientists use the survey results to assess numbers of whales and dolphins and trends in their abundance, which helps determine the degree of protection the species may need.

Unusual species sighted included pygmy killer whales seen for the first time off California and warm-water seabirds such as band-rumped storm petrels seen for the first time in the Northeast Pacific. The survey also sighted sei, blue, fin, humpback, killer and short-finned pilot whales. In one instance the crew could hear a particularly loud chorus of singing humpback whales in the open air on deck.

The abundance of sei whales was a surprise, with more sightings of this species than the last five surveys combined from 1991 to 2008.

The Survey included the first offshore tests of the Drifting Acoustic Spar Buoy Recorder (DASBR), a pioneering system developed at the Southwest Fisheries Science Center to record the calls and other sounds of marine mammals while drifting the open ocean. Crews recover the DASBRs by following a GPS beacon and later acoustic analysis can distinguish the number and density of different species of marine mammals in surrounding waters.

The successful launch and recovery of several DASBRs over the course of the survey helps pave the way for longer-term deployment of the devices that cost less than $5,000 each. DASBRs drift in the open ocean and avoid the engine noise of similar arrays towed behind ships. That allows them to collect more data at a lower cost, supplementing traditional surveys that require expensive ship operations.

New study predicts eastern Pacific species shifting poleward by 30 km per decade

Contributed by Michael Milstein December 10, 2014

Anticipated changes in climate will push West Coast marine species from sharks to salmon northward an average of 30 kilometers per decade, shaking up fish communities and shifting fishing grounds, according to a new study published in Progress in Oceanography.

The study suggests that shifting species will likely move into the habitats of other marine life to the north, especially in the Gulf of Alaska and Bering Sea. Some will simultaneously disappear from areas at the southern end of their ranges, especially off Oregon and California.

“As the climate warms, the species will follow the conditions they’re adapted to,” said Richard Brodeur, a NOAA Fisheries senior scientist at the Northwest Fisheries Science Center’s Newport Research Station and coauthor of the study. “We’re going to see more interactions between species and there will be winners and losers that we cannot foresee.”
Climate models used to project species shifts

The study, led by William Cheung of the University of British Columbia, estimated changes in the distribution of 28 near-surface fish species commonly collected by research surveys in the northeast Pacific Ocean. The researchers used established global climate models to project how the distribution of the fish would shift by 2050 as greenhouse gases warm the atmosphere and, in turn, the ocean surface.

Brodeur cautioned that like any models, climate models carry uncertainty. While they provide a glimpse of the most likely changes in global climate, they may be less accurate when estimating more fine-scale, local changes.

“Nothing is certain,” he said, “but we think we have a picture of the most likely changes.”

Some species shifts are already being documented as West Coast waters are warming: predatory Humboldt squid from Central and South America have invaded the West Coast of North America in recent years, albacore have shifted to more northerly waters and eulachon have disappeared from warming waters at the southern end of their range.
Effects on the marine ecosystem

“Thinking more broadly, this re-shuffling of marine species across the whole biological community may lead to declines in the beneficial functions of marine and coastal ecosystems,” said Tom Okey, a Pew Fellow in Marine Conservation at the University of Victoria and a coauthor of the study. “These declines may occur much more rapidly and in more surprising ways than our expected changes in species alone.”

The study anticipates warm-water species such as thresher sharks and chub mackerel becoming more prominent in the Gulf of Alaska and off British Columbia. Some predators such as sea lions and seabirds, which rear their young in fixed rookeries or colonies, may find the fish they usually prey on moving beyond predators’ usual foraging ranges.

“If their prey moves farther north, they either have to travel farther and expend more energy to get to them, or find something else to eat,” Brodeur said. “It’s the same thing for fishermen. If it gets warmer, the fish they depend on are going to move up north and that means more travel time and more fuel will be needed to follow them, or else they may need to switch to different target species. It may not happen right away but we are likely to see that kind of a trend.”

El Nino years, when tropical influences temporarily warm the eastern Pacific, offer a preview of what to expect as the climate warms.

Shifts in marine communities may be most pronounced in high-latitude regions such as the Gulf of Alaska and Bering Sea, which the study identifies as “hotspots” of change. Cold-water species such as salmon and capelin have narrower temperature preferences than warmer water species, making them more sensitive to ocean warming and likely to respond more quickly.

An intrusion of warm-water species into cooler areas could lead to significant changes in marine communities and ecosystems. The diversity of northern fish communities, now often dominated by a few very prolific species such as walleye pollock, may increase as southern species enter the region, leading to new food web and species interactions.

Albacore tuna have shifted to more northerly waters.

Eulachon have disappeared from warming waters at the southern end of their range.

Humboldt squid from Central and South America have invaded the West Coast of North America in recent years.

According to the study, thresher sharks may become more prominent in the Gulf of Alaska and off British Columbia.

Recently the Pacific Fishery Management Council voted to change the sardine harvest control rule, increasing the upper limit of the sardine harvest fraction from 15 percent to 20 percent.

The decision came after an exhaustive set of scientific workshops and analysis involving more than 60 people, held over the past two years to respond to a research paper that suggested that sea surface temperature (SST) measured at Scripps Pier in Southern California, which had been employed as a proxy for sardine recruitment, was no longer correlated with recruitment success.

But apparently this fact was lost on environmental activists who cried foul to the media, claiming that sardines are crashing, and the management response to the crisis is to just fish harder.

Claims that the council voted for a more aggressive fishing rate miss the point: nothing could be further from the truth. But the truth is complicated.

We know that California’s sardine population is strongly influenced by ocean temperatures: warmer waters tend to increase sardine productivity, while colder waters tend to decrease it.

“The northern sardine stock has been declining for several years due to poor recruitment, and there is concern that it will decline further in the next couple of years,” says Dr. Richard Parrish, one of the authors of the original sardine control rule. “Although no one can predict the environmental conditions that will occur in the future, the pessimistic view is that the northern stock will continue to decline and the optimistic view is that the present warm water conditions will herald increased recruitment.”

“Whichever occurs first,” he adds, “the past, present and management team-recommended sardine harvest control rules were all designed to automatically regulate the exploitation rates both by reducing the quota and reducing the harvest rates as the stock declines, and by shutting down the fishery if the biomass falls below 150,000 mt.”

The original sardine analysis, made in 1998, was updated by a new analysis that found offshore sea temperatures slightly better correlated with sardine productivity than the measurements made at Scripps Pier. Population simulations made with the updated information that included the population increase in recent decades show that the sardine stock is about 50 percent more productive than thought in 1998. The management team therefore recommended raising the upper bound of fishing fraction from 15 percent to 20 percent to account for the new best available science.

But that doesn’t mean that the catch quota for the coming year will be raised. This is a long-term harvest control rule that simply follows better scientific modeling efforts.

The new rules will determine fishing rate just as before: If the temperature is cold, the harvest will be kept low; if the population size decreases, both the harvest rate and the allowable catch will automatically decrease. In fact, the new sardine harvest rule is actually more precautionary than the original rule it is replacing. It does this by producing an average long-term population size at 75 percent of the unfished size, leaving even more fish in the water, vs. 67 percent in the original rule. The original harvest rule reduced the minimum harvest rate to 5 percent during cold periods. The present, very complicated rule, has a minimum rate of 0 percent during cold periods.

What’s more, the harvest fraction will only be applied after subtracting 150,000 mt from the sardine biomass estimated in the next year’s stock assessment.

Bottom line: The California sardine may be the best-managed fishery of its type in the world — the poster fish for effective ecosystem-based management.

The crabs are great. Its just that there aren’t that many of them.

The Oregon Dungeness fishery opened on time on December 1st, after a short season in the San Francisco Bay area, called district 10.

But boats are simply not finding many crabs.

Graph: Seafood Datasearch, based on state and federal data

One fishermen, describing the northern California / Oregon fishery which opened December 1st, said “North of District 10 was the worst opener I can remember. We knew it would be bad, but not this bad.”

Larger vessels that have the ability to move to other fisheries are now leaving the crab fishery, as the catch rates can no longer support their operations.

Meanwhile, the price at the dock has risen to $3.50, and most packers have extended that retroactively back to December 1st, when the fishery opened with an initial price of $3.10.

The upshot is that harvesters are now predicting the Oregon fishery to be down about 40% from last years 14.3 million pounds, and California is likely to be down 50%.

This means that coast wide, certainly for December and Janaury, it is looking like the lowest total landings for dungeness in the last eight years.

Hugh Link, Executive Director of the Oregon Dungeness Crab Commission, said fishermen keep records and know if they are up or down year over year, and that he definitely has the sense that there are fewer Dungeness crabs coming into pots this year, even though fish tickets are still being tallied from the first few days of the season.

Meat fill has been excellent, the fishery opened on time, and there was agreement on price. Only the crabs have not shown up.

The fishery is highly cyclical, so it is quite likely in a few years we will again be talking about heavy supplies of Dungeness. But for this year, the section and crabmeat supplies will be very tight, and what crab is landed later in the year should be going mainly to the live market.

Environmental sustainability was one of the top concerns at the mid-November Asia-Pacific Economic Cooperation (APEC) summit in Beijing, as shown by the potentially groundbreaking climate agreement reached between the United States and China. The fate of the world’s oceans, from issues ranging from climate change to overfishing, was also in the spotlight, being mentioned by Secretary of State John Kerry as one of many challenges facing the Asia-Pacific region. Unfortunately, the solutions we’re focusing on are not enough to solve the problems that our marine environments face.

The APEC summit is the most recent instance in which the US has touted the expansion of marine preserves as a tonic for global overfishing, especially as climate change and ocean acidification threaten to radically alter our ocean ecosystems. This past September, the Administration created the largest marine reserve in the world when it expanded the Pacific Remote Islands Marine National Monument, moving this strategy to the forefront of our international ocean policy. Secretary Kerry hailed this development as “critical” at the summit, going on to note, “most of the fisheries of the world are overfished.”

But Secretary Kerry gets some key facts wrong here. For one, most of the fisheries of the world are not overfished. In 2014, the UN Food and Agriculture Organization (FAO) placed that number at 29 percent, and reported that approximately 70 percent of the stocks that they assessed were being fished within biologically sustainable levels. If the U.S. is going to promote sustainability worldwide, it should acknowledge current management successes.

And more importantly, these Marine Protected Areas (MPAs) aren’t sufficient to solve some of the most pressing issues affecting our oceans, despite our nation’s recent enthusiasm for promoting them.

MPAs are certainly very useful for certain conservation goals. They can protect vulnerable habitats like coral reefs as well as benefit some species of fish that make those habitats their home. But their widespread adoption presents several challenges and raises several concerns. The biggest issue is that—especially in the developing world—people still need to fish. It’s a valuable source of employment, and an even more valuable source of protein. The FAO estimated that in 2011, 2.3 billion people relied on fish as a significant source of animal protein. A shift from seafood to other, land-based food sources like meat and agriculture may actually increase greenhouse emissions and pollution, making these threats to our oceans even worse.

MPAs are also a much more limited tool than currently acknowledged. They do little to help certain stocks of highly migratory fish, like tuna, which don’t remain in any closed area long enough to reap much of the benefits. Even stocks that stay in one place might not benefit for long. With climate change putting increasing pressure on stocks to migrate from their traditional territories to cooler waters, the spatial limitations of an MPA are a poor fit for the habitat changes that are likely to occur. Similarly, MPAs provide little protection against the increasingly prominent effects of ocean acidification. Effectively dealing with these growing climate problems is going to require a long-term strategy that is simply outside the reach of fisheries management.

Fishing isn’t likely to go away anytime soon, and a global conservation strategy that’s too reliant on keeping fishermen out of an ever-expanding set of ocean reserves has some obvious political, economic, and practical limits. Adopting more sustainable management measures for some of the world’s largest fisheries, many of them in APEC member countries, would likely have a much greater impact.

So what’s the best way to address the problem of overfishing and prepare for climate change? We need to promote a combination of strategies at the international level that have worked so well in some of the world’s best managed fisheries, such as New Zealand, Norway, Iceland, and here in the United States. When effectively implemented, measures like limiting the size of fish that can be caught, controlling how much fish is caught, and restricting the ways in which fish can be caught all produce effects similar to those seen in successful MPAs. They also have the benefit of sustaining fishing economies and maintaining fish as a viable source of food.

No conservation measures, whether on climate, or pollution, or overfishing, can be sustainable in the long-term unless they confront economic and political realities. Promoting better fishing, rather than simply displacing or banning it all together, is far more likely to win support among the developing world, which can’t afford to sacrifice a critical way of life.

The squid fishery in California remains robust, and this year’s catch has been unusually strong in Monterey Bay. In a typical season only about 20 percent of market squid are caught off Northern California. But this squid season — which runs from April to March — more than half of the state’s catch have come from north and central coast waters.

By initial estimates, at least 75 percent of the Northern California squid catch came from waters in and around Monterey Bay. Scientists and squid fishermen do not fully understand the reason for this flip.

“For Monterey, it was amazing,” said Diane Pleschner-Steele, executive director of the California Wetfish Producers Association.

There have been other seasons where Northern California outshone Southern California in squid hauls. But, since 1980, all of those years have preceded or fallen during El Nino climate shifts, which bring warm water to the California coast, starting with Southern California and moving north. It’s believed squid follow the cooler water.

The state is not currently in an El Nino pattern. But, it is possible that recent El Nino-like shifts in ocean conditions drove market squid farther north.

“The last couple of years, especially in Northern California, have been good for squid,” said Neil Guglielmo, captain of the 70-foot fishing vessel Triumphal.

Since squid season began April 1, commercial boats have hauled nearly 60,000 tons of market squid through Northern California ports, with a dock value of approximately $38.3 million. This is the largest squid season north of Point Conception in history and more than double the previous record set in the 2002-03 season. This year, Eureka reported its first squid landings.

“We fished squid this year where we never fished before,” said Guglielmo.

For much of this season, Guglielmo took the Triumphal from its home port near Ventura up the coast to Monterey and points farther north to haul in squid. He reported squid as far north as Crescent City.

“We just followed them up there,” said Guglielmo. “There was so much squid.”

This season was also a record for Monterey Bay, with an estimated 45,000 tons of squid caught in its waters, according to marine biologist Briana Brady with the California Department of Fish and Wildlife.

These record hauls also bring welcome economic benefits to ports. The local squid industry supports approximately 1,500 seasonal and full-time jobs, according to Scheiblauer. Ten squid fishing boats are based in Moss Landing and Monterey. In addition to landing fees at wharfs and the dock value of catches, the squid season brings economic benefits in the form of room and board for crew, fuel for boats, ice, cold storage facilities, transportation and processing for each boat’s catch. The Monterey area includes three resident buyers for squid.

“They’re still a big part of our culture and economy,” Scheiblauer said.

Ample food supplies and undisturbed spawning grounds help sustain market squid along the California coast. But, based on past squid fishing seasons, their numbers can still fluctuate along 10- to 15-year cycles, according to Brady.

Market squid are relatively small, often measuring about a foot in length, and prefer to eat small invertebrates, plankton or each other. Their short six- to 10-month lifespan makes it difficult for biologists to estimate the size of the entire market squid population off California to manage the fishery sustainably.

Instead, beginning in the last decade, regulators crafted a squid fishery management policy around a handful of core regulations. No more than 118,000 tons of squid can be harvested in California waters during the annual season. This limit was based off annual squid harvests in the late 1990s and early 2000s.

“We’re happy with that maximum cap,” said Pleschner-Steele. “It’s a good, conservative number.”

The state also uses a limited-entry permit system for squid fishing to control the number of fishing boats in California waters. In addition, marine-protected areas in Southern California and Monterey Bay keep approximately one-third of squid spawning grounds along the coast off limits to fishing. Finally, no commercial vessel may fish for squid between noon Friday and noon Sunday. This weekly moratorium gives squid in non-protected areas opportunities to spawn, according to Scheiblauer.

As of Nov. 20, the statewide catch for market squid is nearly 115,000 tons. Since the maximum squid harvest cannot exceed 118,000 tons, this season is drawing to an early close. Under a voluntary co-management agreement between the squid fishing industry and Fish and Wildlife, larger fishing vessels ceased harvesting squid last month so smaller boats can “mop up” the remaining allotment of squid.

Based on reports from squid fishermen, this year there will still be plenty of squid left behind. But, in the wake of this season’s unusual squid bounty for Northern California, no one is willing to predict what might be in store for next year. In two previous El Nino cycles, desolate squid harvests in Northern California followed one or two years of largesse.

“You could have a boom year like this year and next year there’ll be nothing,” said Scheiblauer.

But, even after those turbulent oscillations, the squid fishery stabilized around a sustainable mean. That long-term trend gives others cause for cautious optimism.

“If the water doesn’t go crazy,” said Guglielmo, “I think we’ll be fine.”

Recently the Pacific Fishery Management Council voted to change the sardine harvest control rule, increasing the upper limit of the sardine harvest fraction from 15 to 20 percent. The decision came after an exhaustive set of scientific workshops and analysis involving more than 60 people, held over the past two years to respond to a research paper that suggested that sea surface temperature (SST) measured at Scripps Pier in southern California, which had been employed as a proxy for sardine recruitment, was no longer correlated with recruitment success.

The original harvest rule reduced the minimum harvest rate to 5 percent during cold periods. The present, very complicated rule, has a minimum rate of 0 percent during cold periods.

What’s more, the harvest fraction will only be applied after subtracting 150,000 mt from the sardine biomass estimated in the next year’s stock assessment. The new harvest rule will still keep fishing limits low in cold-­‐water, low-­‐biomass conditions. The fraction won’t increase unless and until field surveys demonstrate more sardines and the ocean temperature increases substantially above recent levels.

Bottom line: The California sardine may be the best-­‐managed fishery of its type in the world -­‐ the poster fish for effective ecosystem-­‐based management.

In two previous El Nino cycles, desolate squid harvests in northern California followed one or two years of largesse.

“You could have a boom year like this year and next year there’ll be nothing,” said Scheiblauer.

But, even after those turbulent oscillations, the squid fishery stabilized around a sustainable mean. That long-term trend gives others cause for cautious optimism.

“If the water doesn’t go crazy,” said Guglielmo, “I think we’ll be fine.”
